Friedrich Carl Alwin Pockels

Friedrich Carl Alwin Pockels was a German physicist known for his contributions to the field of optics and for his work on electro-optic effects. He is perhaps best known for the Pockels effect, which describes the change in the refractive index of a material in response to an applied electric field. This effect is important in various applications, including the development of electro-optic devices and modulators.
